i To all whom it may concern:

Be it known that I, ALBERT T. BOOTH, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Pipe-Collar, of which the following is a specification.

This invention relates to those sectional collars which are designed to be clasped about steam, water, gas and other pipes near a floor, wall, partition, ceiling or other part for the purpose of concealing the openings through which the pipes extend and provide a trimming for the pipes on the surface from which they emerge or into which they project.

The object of this invention is to provide a very simple and inexpensive separable collar for this purpose which can be made any size and neat and thin, that has concealed fastening means so devised that the sections can be quickly put together about a pipe in comparatively inaccessible places and positions such as close to a Wall, in a corner or near a projection, and which will firmly and securely hold the sections together so that the collar will surely remain in position on the pipe and yet can, if desired, be easily separated for removal without the use of any tool.

The embodiment of the invention has two loops arranged on the back of one section, or oneloop arranged on the back of each section, and tongues arranged on the back of the other section or one on the back of each section, and so projecting that when the parts are put together the tongues will pass into and proj ect through the loops, which tongues are formed of flat strips of metal notched or slitted and bent and twisted in such manner that when thrust into the loops the notched portions of the tongues spring into engagement with the edges of the loops and prevent the sections from being separated until these parts of the tongue are pressed free from the edges of the loops.

Figure 1 of the accompanying drawings shows a front view of a sectional pipe collar which embodies the invention. Fig. 2 shows a rear view of the same. Fig. 3 shows on a larger scale short portions of the plate sections adjacent to the meeting edges, with the tongues and loop separated. Fig. 4 shows a section on the plane indicated by the dotted line 4-4 on Fig. 3.

The collar is shown as comprising two corresponding semi-annular plate-like sections 1 and 2. These sections can be any suitable size, and may have any desired outline or configuration. Each section is preferably stamped to shape from brass, iron or steel or other sheet metal with a small rearwardly turned flange 3 about the outer edge, and a curved bead 4 on the front face about the central opening. Projecting backwardly from the central bead of each section-are the usual spring fingers 5. When the sections are secured together they form an annular collar having a peripheral flange on the back and a circular bead on the front about the pipe openin with spring fingers which are adapted to c asp the pipe and hold the collar from displacement thereon.

Preferably fastened by rivets to the back surface adjacent to the meeting edges of one section are loops 6. Near the meeting edges, on the back face of the other section, and preferably fastened by rivets are tongues 7 that are stamped from stiff resilient metal, such as hard brass, steel or the like. These tongues are so secured that they project outwardly across the meeting edges and are adapted to extend through the loops on the other section for holding the parts together. The tongues, which are substantially the same width as the width of the openings through the loops, have notches 8 cut in their edges, and portions of the tongues adjacent to these notches are bent backwardly so that after the tongues have been thrust through the loops the bent outer edges of these notches will spring back and engage the back edges of the loops and so prevent the tongues from being withdrawn from the loops. The notched edges of the tongues are also slightly twisted backwardly so that the notches are raised slightly above the plane of the back surface of the plate. This causes the notched edges of the tongues to spring backwardly so that the front edges of the notches will engage the inner edges of the loops, for holding the parts together, and yet will permit these notched edges to be sprung toward the back surface of the plate for releasing the notches when it is desired to withdraw the tongues and separate the sections of the plate. Twisting the tongues in this manner also causes one edge of each tongue to bear against the back surface of the plate and the other edge to bear against the inside surface of the loop and thus hold the parts firmly together so that they will not rattle or jar.

The invention claimed is 1. A pipe collar formed of separable sections with loops and tongues fastened to the back surface near the meeting edges of the sections, said tongues having their edges slitted and bent from the plane of the tongues so as to form catches which engage the edges of the-loops for fastening the sections together, substantially as specified.

2. A pipe collar formed of separable sections with loops fastened to the back surface near the meeting edges of one section and tongues fastened to the back surface near the meeting edges of the other section, said tongues having their edges slitted and bent from the plane of the tongues so as to form catches which engage the edges of the loops for fastening the sections together, substantially as specified.

3. A pipe collar formed of separable sections with loops fastened to the back surface near the meeting edges of one section and tongues fastened to the back surface near the meeting edges of the other section, said tongues being twisted with relation to the plane of the back surface of the collar and having their outside edges notched and bent backwardly to form catches for engaging with the edges of the loops when the parts are put together, substantially as specified.
